Hey guys my name is Charlie,
A few weeks ago i bought myself a Phantom 3 Standard which has been great but a lot of the time when i want to use it, the camera looses connection and says something like : "signal transmission lost" but I' still able to control the actual drone but i can't see the camera from my phone... Please help because it's getting very annoying!!!

The transmitter can actually transmit and receive a signal from about 20-30m away even if the antenna is unplugged internally,so you could try and fix it which would void your warranty or you could just send it back and they will ship you a new one.
